The liquid-phase hydrogen peroxide catalytic oxidation of p-nitrophenol was performed with an Fe(III)-resin catalyst. The conversion and mineralization of p-nitrophenol was effectively achieved at mild reaction conditions with the Fe(III)-resin catalyst. It was found that the oxidant concentration, pH, and temperature dominated the degradation rate of p-nitrophenol. The denitration pathway of p-nitrophenol was proposed, in which the concentration of H(2)O(2) and temperature showed strong influence on the conversion of nitrite to nitrate. To study the factors influencing the denitration of p-nitrophenol, a comparable kinetic study was attempted to know the possible denitration pathway of p-nitrophenol. The results of this investigation indicated that denitration was the possible step occurring with the decomposition of p-nitrophenol.
采用 Fe(III)-树脂催化剂对 p-硝基苯酚进行液相过氧化氢催化氧化。在温和的反应条件下，Fe(III)-树脂催化剂能有效地实现对 p-硝基苯酚的转化和矿化。结果表明，氧化剂浓度、pH 值和温度主导着 p-硝基苯酚的降解速率。提出了 p-硝基苯酚的脱硝途径，其中 H(2)O(2)浓度和温度对亚硝酸盐向硝酸盐的转化有强烈影响。为了研究影响 p-硝基苯酚脱硝的因素，尝试进行了可比的动力学研究，以了解 p-硝基苯酚可能的脱硝途径。研究结果表明，脱硝是 p-硝基苯酚分解时可能发生的步骤。
